Once selected, the block can be moved to any location on the workspace. To remove a block, drag it to the recycling bin. Click on the tools on the top panel to select and drag, rotate, lasso blocks to group them, break larger blocks into the next size down, or glue smaller blocks to form the next size up.

Large Bead Frame prompts your child to practice solving multiplication problems using regrouping.

To use Large Bead Frame, click of the 'X' sign. Be sure the auto exchange, at the top of the screen, is clicked on. Start multiplying the units, tens, hundreds, etc. by sliding the beads across the work area.
